4.50\,\text{eV}

. A student calculates its frequency using the approximate value

h = 6.60\times10^{-34}\,\text{J\,s}

rather than the more precise

h = 6.626\times10^{-34}\,\text{J\,s}

. (Use

1\,\text{eV}=1.602\times10^{-19}\,\text{J}

.) What is the percent error introduced in the student’s calculated frequency? (a) +1.0\% (b) +0.37\% (c) −0.37\% (d) +2.0\%
